NEW QUESTION # 53
An administrator manages a FortiGate model that supports NTurbo
How does NTurbo acceleration enhance antivirus performance?
Answer: A
Explanation:
According to the FortiOS 7.6 Administration Guide and Fortinet hardware acceleration (NTurbo) documentation, the correct answer is A.
What NTurbo Is (FortiOS 7.6 - Verified)
NTurbo is a hardware-based acceleration feature available on specific FortiGate models. It is designed to improve antivirus and IPS performance when operating in flow-based inspection mode.
NTurbo works by creating a fast, optimized data path between:
FortiGate ingress interface
IPS/AV engine
FortiGate egress interface
This minimizes CPU involvement and reduces packet traversal overhead.
Why Option A Is Correct
A . For flow-based inspection, NTurbo establishes a dedicated data path to redirect traffic between the IPS engine and FortiGate ingress and egress interfaces.
This is exactly how NTurbo works, as documented:
NTurbo applies to flow-based inspection only
It accelerates IPS and antivirus scanning
It creates a dedicated fast path that bypasses unnecessary processing steps This significantly improves throughput and lowers latency This description matches Fortinet's official explanation of NTurbo.
Why the Other Options Are Incorrect
B . NTurbo creates two inspection sessions
Incorrect. NTurbo does not duplicate sessions; it optimizes the packet path.
C . NTurbo offloads traffic to the content processor (proxy-based)
Incorrect. NTurbo does not apply to proxy-based inspection and does not offload to content processors.
D . NTurbo buffers the whole file and then sends it to the antivirus engine Incorrect. Buffering entire files is a proxy-based behavior, not NTurbo.
NEW QUESTION # 54
Refer to the exhibits.
The system performance output and default configuration of high memory usage thresholds on a FortiGate device are shown.
Based on the system performance output, what are the two possible outcomes? (Choose two.)
Answer: B,D
Explanation:
From the exhibits:
System performance output
Memory used: 90%
Free memory: ~5%
Default memory thresholds (FortiOS 7.6)
memory-use-threshold-green 82%
memory-use-threshold-red 88%
memory-use-threshold-extreme 89%
Because memory usage (90%) exceeds the extreme threshold (89%), the FortiGate enters conserve mode.
Effects of conserve mode (FortiOS 7.6 - verified)
B). FortiGate has entered conserve mode.
Correct
When memory usage exceeds the red/extreme threshold, FortiGate automatically enters conserve mode.
This is exactly the condition shown in the system performance output.
D). Administrators can change the configuration.
Correct
Even in conserve mode:
Administrators can still log in (GUI, SSH, console)
Configuration changes are allowed
FortiGate does not lock configuration access during conserve mode.
This behavior is explicitly documented in the FortiOS 7.6 Conserve Mode section.
Why the other options are incorrect
A). Administrators can access FortiGate only through the console port.
Incorrect
Network access (GUI/SSH) is still available in conserve mode unless otherwise restricted.
Console-only access is not a conserve-mode requirement.
C). FortiGate drops new sessions.
Incorrect (as a general statement)
FortiGate may drop or bypass new inspection-required sessions depending on fail-open/fail-close settings.
It does not universally drop all new sessions, so this statement is not always true.
NEW QUESTION # 55
Exhibits:
You are asked to implement an antivirus profile for files downloaded through FTP, HTTP, and HTTPS.
While testing, you are successful with HTTP and FTP protocols, but FortiGate does not block the file download over HTTPS.
What could be the cause?
Answer: D
Explanation:
"To perform SSL inspection on traffic flowing through the FortiGate device, you must allow the traffic with a firewall policy and apply an SSL inspection profile to the policy. Note that an SSL inspection profile alone will not trigger a security inspection. You must combine it with other security profiles like Antivirus, Web Filter, Application Control, or IPS."
"By default, firewall policies are set with the no-inspection SSL profile. Therefore, any encrypted traffic flows through uninspected... For antivirus or IPS control, you should use a deep-inspection profile. "
"When you use deep inspection, FortiGate impersonates the recipient of the originating SSL session, and then decrypts and inspects the content to find threats and block them . It then re-encrypts the content and sends it to the real recipient. Deep inspection protects from attacks that use HTTPS and other commonly used SSL-encrypted protocols..." Technical Deep Dive:
The correct answer is D . HTTP and FTP are working because FortiGate can inspect those payloads directly with the antivirus profile. HTTPS is different because the traffic is encrypted. If the firewall policy uses only certificate inspection or another non-decrypting SSL mode, FortiGate can identify certificate/SNI information, but it cannot see the downloaded file contents. Without decrypting the HTTPS session, the antivirus engine never receives the payload to scan, so EICAR or other malware can pass.
Why the other options are wrong:
* A is not the issue here. The exhibit shows the antivirus profile and policy are already aligned for proxy- based operation, and the failure is specific to HTTPS visibility.
* B is wrong because web filter is not required for antivirus scanning.
* C is wrong because firewall policies commonly use ACCEPT with security profiles; the antivirus engine can still block the file after policy match. The study guide explicitly says ACCEPT allows the session and then applies antivirus scanning and other packet-processing features.
To fix it, apply deep-inspection on the firewall policy:
config firewall policy
edit < policy-id >
set ssl-ssh-profile " deep-inspection "
set av-profile " HTTP_AV_Profile "
next
end
On real FortiGate hardware, this also has performance implications. Simple flow handling can often stay on accelerated paths, but full SSL deep inspection forces decryption and content scanning through the inspection engine, increasing CPU/WAD workload.
NEW QUESTION # 56
Refer to the exhibits. An administrator has observed the performance status outputs on an HA cluster for 55 seconds.
Which FortiGate is the primary?
Answer: B
Explanation:
The HA configuration shows that override is disabled (set override disable), but despite this, HQ- NGFW-1 has the higher priority (200) and is acting as the primary, as indicated by its higher resource usage and uptime. Override allows the device with higher priority to take over as primary, so HQ- NGFW-1 is the primary device.
NEW QUESTION # 57
Refer to the exhibit.
What would be the impact of these settings on the Server certificate SNI check configuration on FortiGate?
Answer: C
Explanation:
Based on the exhibit and the FortiOS 7.6 SSL/SSH Inspection documentation, the correct answer is C.
Understanding the Exhibit Configuration
In the SSL/SSH Inspection Profile, the following settings are shown:
Inspection method: Full SSL Inspection
Server certificate SNI check: Strict
This setting directly controls how FortiGate validates the Server Name Indication (SNI) provided by the client during the TLS handshake.
FortiOS 7.6 Behavior of "Server certificate SNI check"
FortiOS supports three modes for Server certificate SNI check:
Disable
No validation between SNI and server certificate.
Enable
FortiGate checks SNI against the certificate.
If mismatch occurs, FortiGate may still allow the session with reduced validation.
Strict
FortiGate enforces a strict match.
The SNI must match either the CN (Common Name) or one of the SAN (Subject Alternative Name) entries in the server certificate.
If the SNI does not match either CN or SAN, the TLS session is immediately terminated.
The exhibit clearly shows Strict selected.
Why Option C is Correct
With Strict enabled, FortiGate rejects the TLS connection when:
The SNI does not match the CN, and
The SNI does not match any SAN entry
This results in the connection being closed, not allowed with warnings or fallback behavior.
Therefore:
C). FortiGate will close the connection if the SNI does not match the CN or SAN fields is exactly the documented behavior.
Why the Other Options Are Incorrect
A: FortiGate does not fall back to using the CN for URL filtering when Strict is enabled.
B: There is no "accept with warning" behavior in Strict mode.
D: Incorrect logical condition. FortiGate does not require mismatch with both CN and SAN simultaneously; a mismatch with either valid field set is sufficient to close the connection.
